Lemans Posted November 19, 2006 Share Posted November 19, 2006 Hi there i have a 1980 gt galant with a 4g63t sirius 80 engine. I want to put a 12 valve head on it but all i can find is a head of a gsr 3 starion but the the inlet manifold will not bolt on. The dash motor is wide block so the head of it will not fit mine.Does any head exist that will bolt on to my block and take my manifolds ?

lowlancer Posted November 19, 2006 Share Posted November 19, 2006 12 valve head is probably more trouble than it's worth anyway Twin cam head conversion from VR4 is popular in OZ, but involved. I'd just do the whole twin cam conversion like macabre on these forums, or source a complete 12 valve motor like I have. Problem with 12 valve is they are pretty rare, and don't share a lot of things like inlet etc with 8V Quote Link to comment Share on other sites More sharing options...
